Hi,
I used a Listbox and I want to drag and drop items into it to reorder them. I used RadDragAndDropManager. I have seen in your samples (http://demos.telerik.com/silverlight/#DragAndDrop/TreeToGrid) that there is a dragcue with the TreeViewDragCue to see where the selected item will be dropped. But when I use the TreeViewDragCue in a Listbox the behavior is different. Is it possible to have the same with a Listbox ?

Hello Audrey,
The drop indicator in the example of the treeview. In order to create similar experience to the listbox you can follow this help article - http://www.telerik.com/help/silverlight/raddraganddrop-between-listboxes-with-user-feedback.html
Kind regards,

Thank you.
But I want to use a WrapPanel into my Listbox as a ItemsPanelTemplate. In this case the DragCue stay on the left and it don't follow the drag action. Do you have an idea to solve my problem ?

Thank you very much.
It's exactly what I wanted but if I want to select multiple items, only one item is sent to the playload property. How can I do to manage drag and drop for multiple items ?

Hello Audrey,
I can suggest one additional option in addition to the one, I have suggested in the other thread. You can inherit Microsoft listbox and it mode similar to DragElementAction of our RadGridView. Thus it will have the ability to suppress clearing selection when clicking on selected item.
Please check the attached project. If you select multiple items from the first ListBox and click on the selected item the selection will not be cleared.
